Xvive U2 Manual page 13

The U2 operates in the 2.4 GHz ISM band, the same band
used by Wi-Fi, Bluetooth, and other wireless systems.
2.4 GHz is an open band and as such does not require a
license to operate worldwide.
Tips and Methods to improve the performance of the
wireless system
1) Keep more than 3 meters distance between the U2
receiver and other transmitters such as WiFi routers.
2) Change channels to avoid interference with other
WiFi systems.
3) In case of interference from other WiFi systems, shorten
the distance between the U2 receiver and transmitter.
2.4 GHz WIRELESS OVERVIEW AND INTERFERENCE
2.4 Ghz Frequency Tables
CHANNEL 1 2402 MHz, 2480 MHz, 2482 MHz
CHANNEL 2 2408 MHz, 2472 MHz, 2474 MHz
CHANNEL 3 2420 MHz, 2456 MHz, 2458 MHz
CHANNEL 4 2432 MHz, 2448 MHz, 2450 MHz
U2 channels 1-4 use the same frequencies as U3/U3C/U4
channels 1-4. A maximum of six U2/U3/U3C and U4 sets
can be used at the same time.
